Define HAVE_SOME_SNMP if either HAVE_UCD_SNMP or HAVE_NET_SNMP is defined, and use HAVE_SOME_SNMP, rather than HAVE_UCD_SNMP, in most places when testing whether we have an SNMP library or not. Be more selective when including Net-SNMP header files. Fix up {gtk,gtk2}/main.c to do the same SNMP stuff that tethereal.c does - including the MIB stuff that gtk/main.c was doing but gtk2/main.c wasn't doing. Fix the copyright date in gtk/main.c. svn path=/trunk/; revision=6483

* Oh, this is hellish.
|
|
*
|
|
* The CMU SNMP library defines an OID as a sequence of "u_int"s,
|
|
* unless EIGHTBIT_SUBIDS is defined, in which case it defines
|
|
* an OID as a sequence of "u_char"s. None of its header files
|
|
* define EIGHTBIT_SUBIDS, and if a program defines it, that's
|
|
* not going to change the library to treat OIDs as sequences
|
|
* of "u_chars", so I'll assume that it'll be "u_int"s.
|
|
*
|
|
* The UCD SNMP library does the same, except it defines an OID
|
|
* as a sequence of "u_long"s, by default.
|
|
*
|
|
* "libsmi" defines it as a sequence of "unsigned int"s.
|
|
*
|
|
* I don't want to oblige all users of ASN.1 to include the SNMP
|
|
* library header files, so I'll assume none of the SNMP libraries
|
|
* will rudely surprise me by changing the definition; if they
|
|
* do, there will be compiler warnings, so we'll at least be able
|
|
* to catch it.
|
|
*
|
|
* This requires that, if you're going to use "asn1_subid_decode()",
|
|
* "asn1_oid_value_decode()", or "asn1_oid_decode()", you include
|
|
* "config.h", to get the right #defines defined, so that we properly
|
|
* typedef "subid_t".
